The Greek Institute, 1038 Massachusetts Avenue, is tucked among modern buildings in Cambridge. It is crammed full of books by Greeks and on Greek and Greece. It has no association with Harvard. It attracts both Greeks and philhellenes and offers classes in modern Greek and organizes concerts and exhibitions. My talk was in a gallery where Richard Moore’s photographs “Athens Twice Seen” were on exhibit. Richard and his wife, Emily, were there, as well as Therese Sellers, a friend from Twitter, and Andreas, the guy who lives in the top half of the house. I knew I was in the right place when I saw Athens Street and a pub called Dedalus.
